For easy of extensibility to future chips, below data and functions applicable to T23x are moved to dev-t18x.c - chip data for supported chips - set_boot_vec: set up EVP - set_boot_freqs: set ADSP freq as per DT property - check_wfi_status: check WFI status from AMISC - dump_core_state: ADSP core and state dump Bug 3682950 Change-Id: Iffba56addc9a68ec33de390a379fe725e727cfad Signed-off-by: Viswanath L <viswanathl@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nv-oot/+/3107450 GVS: Gerrit_Virtual_Submit <buildbot_gerritrpt@nvidia.com> Reviewed-by: Dara Ramesh <dramesh@nvidia.com>
